Eglantine Boulard


My research activity mainly focused on the study of the deep Earth interior. I use mineral physics in order to address key questions about the deep Earth by determination of materials properties at the high P-T conditions existing within our planet. Throughout my research, I have used a large number of probes, which when combined together allowed me to fully characterize the crystallography and chemistry of the materials investigated.
